I have the same adapter and I just use the adapter + ahead-style-stem as a quill stem.
I am confused - are you primarily concerned with the aesthetic issues with having the stem raised up? And are you sure there is no min-insertion line on the quill?
Edit:
I actually have
this adapter, not the Profile one. My mistake. I believe the minimum insertion mark is usually 2X or 2-1/2X the quill diameter.
Here is what
Sheldon Brown had to say about quill stems:

Most stems have a "minimum insertion" mark that shows how high it may safely be set. If you can see this mark, the stem is too high. If your stem doesn't have such a mark, a good rule of thumb is that there should be at least 2 inches/50 mm of stem inside the fork.
